IMPROVEMENT IN STEAM-ENGINE GOVERNORS.

Specification forming part of Letters Patent No. 511,05 7, dated April17, 1866.

To all whom it may concern Be it known that I, J. C. CLINE, ofPhiladelphia, Pennsylvania, have invented certain Improvements inGovernors for Steam-Engines 5 and I do hereby declare the following tobe a full, clear, and exact description of the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon.

My improved governor consists ota spindle, sleeve, weighted arms, andsprings, the whole being constructed and arranged for joint actionsubstantially as described hereinafter.

In order to enable others to make anduse my invention, I will nowproceed to describe its construction and operation.

On reference to the accompanying drawings, which form a part of thisspecification, Figure l is an exterior view ot' my improved governor;Fig. 2, a sectional elevation, and Fig. 3 a plan view.

Similar letters referto similar parts throughout the several views.

In suitable bearings a a turns the spindle A, and near one end of thelatter are jointed two arms, B B', which are bent to the form shown inthe drawings, and at the outer end ot' each arm is a spherical weight,b. On the spindle A slides a sleeve, C, the movement of which in 011edirection is limited by a collar, c.

'Ihe usual devices may be employed for con necting the sleeve to theregulating-valve ot`a steam-en gine.

A spring, D, is secured to the sleeve by a nut, on, the springpresenting two elastic plates, by which alone, in place of the usualrigid rods, the sleeve is connected to the weighted arms B and B', eachend of the spring projecting into a slot in one of the arms, where it issecured by a pin, c, the spring tending to maintain the arms in theposition shown in Fig. 2.

As the arms B B' are thrown outward by centrifugal force when a rotarymot-ion is imparted to the governor the sleeve must ot` necessity bemoved, the spring at the same time yielding and accommodating itself tothe dit'- ferent relative positions assumed by the arm and sleeve.

In governors of the usual form the arms B B are connected to the sleeveby rigid rods, and one or more springs are sometimes ap- 'plied to thegovernor, and tend to force the arms toward the spindle.

It will be apparent that by substituting the spring D for the usualconnecting-rods, as in v the above-described governor, the same resultsare attained as where both springs and connecting-rods are used, whilethe governor is less complicated, more compact, and less expensive.

It will also be seen that by making the arms B Bl ofthe bent formrepresented ample room is afforded for a spring ot' appropriate lengthand the desired elasticity.

I wish it to be understood that I do not claim, broadly, thecombination, with the governor, of springs connected directly to theballs ofthe same; but

I claim as my invention and desire to secure by Letters Patent- Thewithin-described governor, composed ot' a spindle, A, sleeve C, weightedarms B B, and spring I), the whole being constructed and arranged forjoint action as and for the purpose herein set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribin g Witnesses.
